The Damage Supervision And Reinforcement Of Existing Bridge

With the continued development of the bridge construction, bridge structure, form andfunction are becoming increasingly complex, the repair and reinforcement of thebridge is also more and more attention. After the bridge was opened to traffic, due tothe impact of climate, environmental factors and human factors, the structure of thematerial will be corrosion and gradually aging, long-term static and dynamic loads, itsstrength and stiffness decreases with increasing time. Not only will more make theservice life of the bridge shortened the more serious will affect traffic traffic safety,crisis of human life. Detection and monitoring of the bridge structure as the structuralsafety of maintenance, the attention of one of the normal use of the guaranteemeasures, quality testing and safety monitoring of bridge structures has become a hotacademic circles at home and abroad, the engineering research. The main contents ofthis paper are as follows：（1） for both bridge damage identification theory expounded, summed up thetype of injury, especially now more and more extensive application of prestressedconcrete bridge damage described and summarized in the concrete structure of thebridge damage reason.（2） elaborated how both bridges to detect the specific content and to introducethe theory of bridge visual inspection,concrete strength testing,the bridge staticloading test with dynamic load test detection theory, summarizes the theory of thenow commonly used in bridge inspection and methods.（3） measures to reinforce the main bridge for both operators statementreinforced the principle, and the reinforcement of the means of transformation.Summarizes the existing bridge reinforcement methods, as well as their owncharacteristics and scope of reference for the existing bridge reinforcement.（4） combine theoretical study of this article, dynamic load testing engineeringinstances, dynamic loading of both a city bridge damage detection as the basis foranalysis, the use of the detection method mentioned in this paper, simultaneouslyreinforced envisioned.
